Diagnosis. A genus of Mariametridae with centrodorsal thin, discoidal; radials partly or completely concealed by centrodorsal; cirrus sockets restricted to centrodorsal margin, not encroaching on broad aboral pole; brachitaxes separated or in close lateral apposition; brachitaxis ossicles usually thickened laterally, producing characteristically apposed flattened margins, sometimes weakly crenulate, or weakly thickened with margins not apposed; cirri of <35 cirrals; distal cirrals smooth or bearing aboral carination that may develop into a low triangular spine; P1, P2 and sometimes P3 with reduced ambulacral groove; P2 largest, tapering to finely flagellate tip; pinnulars barely longer than broad; articular facets normally developed.
